Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed October 25, 1913. Serial No. 797,187.

To all whom it may concern Be it known that I, FRANK E. SHAILOR, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Connector-Plu s for Electrical Instruments, of which the ollowing is a specification, reference being had therein to the accompanying drawings.

The invention relates to connectors for electrical instruments, such as used for electrically-heated sad irons and similar devices, and it is the object of theinvention to provide means for guiding the plug into engagement with the terminal contacts, as well as releasing the latter from mechanical stresses.

To this end the invention comprises the construction as hereinafter set forth.

In the drawings: Figure 1 is a perspective view of an electrically-heated sad iron with the improved connector applied thereto; Fig. 2 is a cross section through the plug and guide; Fig. 3 is a side elevation of Fig. 1, showing the parts in engaged position; and Fig. 4 is an elevation of the guide showing a modified construction.

A is the casing of the sad iron or other instrument to be heated. B is the handle therefor, which, as shown, is attached to the casing by metallic arms or brackets C and C.

D are the terminal contacts projecting outward from the case in rear of the bracket C, and E is the connector plug for engaging with said contacts.

To guide the plug while being engaged with the contacts and also to hold it in engaged position, so as to relieve stress from said contacts, I have formed upon the side of the plug and preferably upon each side as shown in Fig. 2 parallel flanges F, which are adapted to enga e the opposite edges of the arm or bracket This arm is therefore formed with a ortion G which is parallel to the contacts and a bent portion H extending to the handle. Adj acentto the bend the portion H is cut away at its opposite edges, as indicated at I, so as to provide clearance for the engagement of the flanges F with theportion To securely fasten the flanges F to the plug, and also to increase the strength of the latter, a metallic strap J is bent to embrace the insulator body K and to extend downward upon opposite sides thereof. This strap is provided with ears from which the flanges F are struck up, while screws L, passing centrally through the body and the opposite sides of the strap, clamp the parts in fixed position.

The guides F are preferably formed upon opposite sides of the plug, so that the latter is reversible and in either position may be engaged with the guide G.

As shown in Fig. 4, the guide portion G of the handle supporting arm or bracket may be formed with struck-out ears G for engagement with the flanges F. This avoids necessity of cutting away the bracket at the bend and permits of the free engagement and disengagement of the guides.

What I claim as my invention is:

1. The combination with an electricallyheated instrument of a terminal contact therefor, a handle bracket extending parallel to said contact, and a detachable connector plug slidably interlocking directly with said parallel portion of said brackets to be guided thereby into engagement with said terminal contact.

2. The combination with an electricallyheated instrument, of a terminal contact projecting therefrom, a handle bracket extending parallel to said contact, an insulator connector plug, and a metallic guide upon said plug slidably engageable with the parallel handle bracket, to be guided thereby into engagement with said terminal contact.

3. The combination with an electricallyheated instrument of a terminal contact projecting therefrom, a handle bracket having a portion extending parallel to said contact and a bent portion for attachment to the handle, a plug connector, and guides upon said connector for embracing the parallel portion of said handle bracket to guide said plug into engagement with said terminal contact.

4. The combination with an electricallyheated instrument of a terminal contact projecting therefrom, a handle bracket having a portion extending parallel to sald contact, a plugconnector and guides on opposite sides of saidplug for alternativeengagement with said parallel portion of the bracket to guide said plug into engagement with said terminal contact.

5. The combination with an electricallyheated instrument of a terminal contact projecting therefrom, a handle bracket having a portion extending parallel to said ter minal contact, an insulator connector plug, a metallic strap embracing said plug, and guides struck-up from opposite sides of sa1d strap for alternatively engaging said parallel portion of the handle bracket. to guide said plug into engagement with sa1d terminal contact.

6. The combination with an electricallyheated instrument of a terminal contact -pro jecting therefrom, a handle bracketformed of 'a flat bar having a portion extending parallel to said terminal contact and a bent portion for connecting with the handle, the opposite sides being narrower at the bend, and a terminal plug provided with spaced guides for embracing the opposite edgesof said parallelportion of the handle bracket and adapted to enter into engagement therewith over the narrower bent portion thereof.

7. The combination with an electricallyheated instrument of a pair of terminal contacts projecting therefrom, a handle bracket formed of a flat bar having a portion extending-parallel and adjacent to said terminal contacts, with a bent portion extending to the handle and narrower at the bend than said parallel portion, and a connector plug having hooked guide flanges for embracing the opposite edges of said parallel portion of the handle bracket and engageable therewith at said narrower bend.

8. The combination with an electricallyheated instrument of a terminal contact projecting therefrom, a handle bracket formed of a flat bar havinga portion extending par allel to said terminal contact and a bent portion for connecting with the handle, the opposite sides of said parallel portion being struck-out to increase the width, and a terminal plug provided with spaced guides for embracing the struck-out opposite edges of said parallel portion and adapted to enter into engagement therewith over the narrower portion at the bend.

9. In an electric laundry-iron, a body; a standard arranged over the rear portion of and secured to sa1d body and instrumental I in supporting a grip-member; two laterally spaced terminal pins rearward of and spaced from the lower portion of said standard and extending upwardly from and secured to the body; a terminal plu'g'slipped onto and mov- "ablejupwa'rdly from the pins, and a plate "arranged at the rear face of and secured to said plug and provided with two arms arranged at opposite sides respectively of the plug and having members extending over the forward side'of said standard, thestandnetting contoured and arranged to permit movement of sa1d arms upwardly fromthe standard during removal of the plug from the pins.
